[PATCH] hw_random: mediatek: Setup default RNG quality

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Sean Wang <sean.wang@xxxxxxxxxxxx>

When hw_random device's quality is non-zero, it will automatically fill
the kernel's entropy pool at boot.  For the purpose, one conservative
quality value is being picked up as the default value.
